 Unit validate(SenderCertificate certificate, Long validationTime)
```
    Validates certificate.
    The default behavior checks the certificate against each key in trustRoots in constant time (that is, no result is produced until every key is checked), making sure one of them has signed its embedded server certificate. The validationTime parameter is compared numerically against SenderCertificate.expiration and is not required to use any specific units, but Signal uses milliseconds since 1970.
  - validate
```
 final Unit validate(ServerCertificate certificate)
```
    Verifies a ServerCertificate against the set of trust roots.
    This is only meant for convenience in unit testing and thus is not a constant-time operation. It is not used by SealedSessionCipher.
